Embodiment 1：
During in order to solve in the prior art to be locked to workpiece using unit bolt nut, specific purpose tool is needed,
The problem of cumbersome, and nut is difficult to dismantle when corrosion occurs for wet environment, the present embodiment provides the locks as shown in Fig. 1 ~ 5
Tight component, including fixed plate 1, bolt 2, movable rotation-shaft 3, bottom plate 5 and rotational handle 6, fixed plate 1 and bottom plate 5 are individually fixed in
It needs on lock two workpiece 13.The both ends of movable rotation-shaft 3 respectively have there are one through-hole, and bolt 2 passes through 3 one end of movable rotation-shaft
It is fixed on after through-hole in fixed plate 1, can be relatively rotated between movable rotation-shaft 3 and bolt 2.
More specifically, the tail end of bolt 2 is equipped with screw thread for being fixed with workpiece 13, the middle part of bolt 2 is the light of non-threaded
Bar portion is used for the through-hole across 3 one end of movable rotation-shaft, coordinates for small―gap suture therebetween, length and the movable rotation-shaft 3 in polished rod portion
Thickness it is equal, the top of bolt 2 is equipped with interior hexagonal twisting slot 14.Polished rod portion reduces opposite between movable rotation-shaft and bolt turn
Frictional force when dynamic, the design of twisting slot is that bolt is installed for convenience.
On the leading flank of bottom plate 5 there is a chamfered region, there is limiting slot in chamfered region；The length of chamfered region can be with
Entire leading flank is occupied, can also only be set in front face subregion, inclined-plane is longer, applicable two distant workpiece
Fastening.
The tail portion of rotational handle 6 contacts after passing through the through-hole of 3 other end of movable rotation-shaft with the chamfered region on bottom plate 5, and
Rotational handle 6 is fixedly connected with movable rotation-shaft 3.When pushing the head of rotational handle 6, rotational handle 6 drives movable rotation-shaft 3 with spiral shell
Bolt 2 is rotated for the center of circle, while the tail portion of rotational handle 6 is slided along chamfered region, and when the tail portion of rotational handle 6 enters limiting
When in slot, 3 position of movable rotation-shaft is fixed, and fixed plate 1 and bottom plate 5 drive two workpiece 13 close and lock at this time.
More specifically, as shown in Fig. 2, chamfered region on 5 leading flank of bottom plate is stepped in two-stage, first including recess
Second inclined-plane 8 on inclined-plane 7 and protrusion, has several first limiting slots 9 on the first inclined-plane 7, corresponding position on the second inclined-plane 8
With several the second limiting slots 10.A ball 4 is fixedly mounted in the tail end of rotational handle 6, and ball 4 is fixed by screw or jackscrew
Mounted on the tail end of rotational handle 6.
When the first limiting slot and the second limiting slot are one, in the position for setting the first limiting slot, the second limiting slot
When, the distance that is just tensed according to the needs of two workpiece sets the gradient on inclined-plane and the position of limiting slot, ball from starting point to
The distance that second limiting slot is tensed is exactly the distance that two workpiece actual needs tense.
In order to improve production efficiency, multiple first limiting slots can also be set on the first inclined-plane, while on the second inclined-plane
When the distance between multiple corresponding second limiting slots of upper setting, two workpiece are different, ball is moved to by rotational handle
In the second different limiting slots.
When the tail portion of rotational handle 6 is slided along chamfered region, the middle part of rotational handle 6 is slided along the second inclined-plane 8, rolling
Pearl slides along the first inclined-plane 7, and when the middle part of rotational handle 6 enters the second limiting slot 10, ball 4 enters the first limiting slot 9 just,
And second limiting slot 10 bottom be higher than the first inclined-plane 7 bottom, so as to which ball 4 be avoided to slip into the second limiting slot 10.Ball
Position is defined with rotational handle, so as to fulfill being relatively fixed between bottom plate, movable rotation-shaft, rotational handle and fixed plate,
With regard to realizing the reliable locking to two workpiece 13.
The locking process of this locking device does not need to specific purpose tool, directly can be realized with hand push turn fixed handle, effectively
Complex installation process when solving classic screw and nut check it is difficult, it is more to expend working hour, when working environment complexity, nut
The problems such as corrosion occurs being difficult to dismantle or can not dismantle.
In order to match different workpiece, fixed position of the rotational handle 6 on movable rotation-shaft 3 is adjusted, and therefore, activity turns
Top wire hole 11 there are two tools on axis 3, rotational handle 6 realize phase by the jackscrew 12 and movable rotation-shaft 3 being mounted in movable rotation-shaft 3
To fixation.There is different embodiments that can realize to be relatively fixed, for example, it may be jackscrew 12 passes through the end of top wire hole to be against
In rotational handle, so as to which rotational handle 6 with movable rotation-shaft 3 be fixed or multiple corresponding jackscrews are set in rotational handle 6
Hole, jackscrew sequentially pass through movable rotation-shaft 3 and rotational handle 6；When applied to different workpieces, first according to the relatively high of workpiece planarization
Degree adjusts the position of rotational handle and then fixes rotational handle with jackscrew.
The locking device of embodiment 1 to install and use process as follows：
Bottom plate is installed on an object with screw, and fixed plate is mounted on screw on another workpiece.Movable rotation-shaft by
Bolt is fixed in fixed plate, and movable rotation-shaft can be rotated around the bolt.Rotational handle is packed into the other end through-hole of movable rotation-shaft
It is interior, the position of rotational handle is adjusted, and fixed with jackscrew, ball screw or jackscrew are fixed on rotational handle tail end, ensured
Ball moves together with rotational handle.
At work, rotational handle is pushed to carry out linear slide along the second inclined-plane on bottom plate, while ball is the bottom of along
The first inclined-plane on plate carries out linear slide, and when rotational handle is moved with ball along inclined-plane, movable rotation-shaft can further
The distance of fixed plate and bottom plate, and fixed plate and bottom plate are separately fixed on a workpiece, and then between two workpiece that further
Distance, when the distance between two workpiece sufficiently closes to, rotational handle moved to simultaneously with ball corresponding second limiting slot and
In first limiting slot, rotational handle is limited with ball, and two workpiece are locked simultaneously.
Classic screw is effectively solved with complex installation process during nut check with difficult, consuming working hour is more, works as building ring
During the complexity of border, the problems such as occurring being difficult to dismantle or can not dismantle.
The above content is combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, several simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
